The Triumph Speed T4 is a motorcycle from Triumph. It is currently on sale. With a 349 cc engine it sits in the 250–450 cc class.
Power comes from a 349 cc single-cylinder liquid-cooled engine that makes 28.6 bhp at 7,500 rpm and 31 Nm of torque at 5,500 rpm. Its bore is wider than its stroke (89 mm x 56.1 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 161 PS per tonne; by that measure, it is lively, with easy overtakes and relaxed highway speeds. The claimed top speed is 137 km/h. It has electric start.
It has a 6-speed manual gearbox with a 1-down, 5-up shift pattern, and a chain carries drive to the rear wheel. Its slipper clutch lightens the lever and stops the rear wheel hopping when you downshift hard.
At the front, the suspension is 43mm conventional fork 140mm wheel travel. At the rear, it is gas monoshock RSU with external reservoir and pre-load adjustment. Braking is by a 300 mm disc at the front and a 230 mm disc at the rear, with dual-channel ABS. ABS on both wheels keeps either tyre from locking under hard braking. It rides on 17-inch alloy wheels with tubeless tyres — 110/70 - 17 at the front and 140/70 - 17 at the rear.
The seat is 806 mm off the ground, which is about average and suits most riders. It weighs 180 kg ready to ride, which is on the heavy side, so moving it by hand takes some effort. Ground clearance is 170 mm — enough for most speed breakers. The wheelbase is 1,416 mm. It carries 13 L of fuel.
Equipment includes a semi-digital instrument console, an LED headlamp, gear position indicator, service due indicator, engine temperature indicator, low fuel indicator and low oil indicator. Safety equipment includes engine kill switch, side-stand engine cut-off, side-stand warning and malfunction indicator.
